Latest Centromere Stories
New York University biologists have identified how a vital protein is loaded by others into the centromere, the part of the chromosome that plays a significant role in cell division.
Scientists at the Stowers Institute of Medical Research have developed an innovative method to count the number of fluorescent molecules in a cluster and then applied the novel approach to settle a debate rampant among cell biologists—namely, how DNA twists into a unique chromosomal structure called the centromere.
Researchers at the University of California, San Francisco and the Stowers Institute for Medical Research have discovered that planarians, tiny flatworms fabled for their regenerative powers, completely lack centrosomes, cellular structures that organize the network of microtubules that pulls chromosomes apart during cell division.
All 10 trillion cells in the adult human body are genetically identical, but develop into distinct cell types, such as muscle cells, skin cells or neurons, by activating some genes while inhibiting others.
A cell's genome maintains its integrity by organizing some of its regions into a super-compressed form of DNA called heterochromatin.
The Agricultural Sciences Network Life-Sciences.net features the latest scientific publications in this discipline.
Centromeres are specialised regions of the genome, which can be identified under the microscope as the primary constriction in X-shaped chromosomes.
After more than a century of study, mysteries still remain about the process of meiosis—a special type of cell division that helps insure genetic diversity in sexually-reproducing organisms.
Researchers at IRB Barcelona discover a crucial mechanism controlling the segregation of genetic material from parent to daughter cells.
Researchers from Trinity College Dublin have uncovered the evolutionary mechanisms that have caused increases or decreases in the numbers of chromosomes in a group of yeast species during the last 100-150 million years.
